Hi I'm realeasing some textures under the GNU-GPL v3 CC-BY-NC-SA-4.0. (I hope its liberal enough for you to make use of it)
Tell me what you think or maybe you got a cool idea you want me to turn into a texture. (sketch mby?)
I'll keep releasing textures here as they happen or you could also release them here if you'd like to have a place for that.
(there is also an experimaental gold texture where I tried applying an envmap to the glossy part but idk)

Bumpitybump. LOL
Anyways made color variants to the texture. It's easier than I thought. Here's a screenshot of my texture program showing the different colors (and how easy it is - any requests?).
So color requests are easy and shape requests are just as easy. The original plan with that texture was to have a lava-look-alike and maybe later have a map full of textures that look familiar but aren't.
